As you no doubt know, some people believe that chrome lining cannot be made as consistent (E.G.: accurate) as an unplated barrel and that optimum (match) accuracy would preclude a chromed bore.
I have a chrome lined 1963 TRW barrel on my M1A, with handloads she'll shoot 1" groups at 100 yards. Some factory ammo is terrible though, Federal Gold Medal Match shot 10'' groups at 100 yards.
